Answer: 3-5x
4/5
4
Step-by-step explanation: if we say y=(-x+3)/5 to take the inverse:
we need to leave x alone
5y=-x+3
5y-3=-x as to x=3-5y
now we can say that inverse of g(x) is equal to 3-5x
for Q2
x=1 for 3-5x
and that is 3-5*1=-2
now X=-2 for -x+3/5 and that is 4/5
for last one we need to find y=0 (bc of inverse function)
